CAR-WH EEL.

SPECIFICATION forming part of Letters Patent No. 634,280, dated October 3, 1899.

Application filed December 7,1898. Serial No. 698,522. (No model.)

To coll-wharf@ it may concern:

Be it known that I, JONATHAN B. lVEST, a citizen of the United States, residing at Rochester, in the county of Monroe, in the State of New York, have invented an Improvement 4in Oar-VVheels, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain improvements in the construction of car-wheels having compressed tires whereby their manufacture is simplified and cheapened and the tires are more securely held on thewheel-centers.`

My improvements are fully described and illustrated in the following specification vand the accompanying drawings, the novel features thereof being specified in the claims annexed to the said specification.

In the accompanying drawings, Figure lis a radial section of the tire. Fig. 2 is a radial section of the tire and a portion of the wheelcenter.

In the practical application of my invention I form the tire A of any ordinary or suitable shape, and I provide it on its inner corners with the continuous inwardly-proj ectin g flanges B and C. Such a tire may be formed by rolling with rolls of suitable shape. 'Ihe flange B on the outside of the wheel is preferably made heavier than that on the inside, (shown at C.) The wheel-center D, which may be of any suitable pattern or dimensions, is provided with the usual flange E around its periphery, and the outer edges or margins of the flange are beveled outward,as indicated at F F. These bevels are easily produced in turning the wheel-center. The width of the ange E, measured at the points of the bevels, corresponds with the distance between the inner faces of the flanges B and C on the tire. The diameter of the liange C is such as to permit the wheel-center to be placed inside the tire. After the tire has been applied to the wheel-center the tire is subjected to compression by any suitable mechanism-such, for instance, as the hydraulic tire-setter described in my Patent No. 520,817, dated .I une 5, 18M-so that it is upset or shortened in circumference and its inner surface pressed with any desired degree of force against the face of the wheel-center. This compression of the tire is represented by the full and dotted lines in Fig. 2. After the compression the bevels F ,E come inside the flanges B and C, and in order to secure the tire to the wheelcenter these flanges are bent down over the bevels, as indicated in Fig. l.

The operation of bending the flanges over the bevels maybe performed by rolling, hammering, or in any other suitable way, and the iianges may be bent at the same time or one after the other.

It should be noted that by this method of manufacturing car-wheels the pressure can be regulated with exactness, the object being to prevent such a contracting effect upon .the wheel-body as would impair it or possibly disrupt it, as might be the case if the tire were applied hot and the iianges pressed down in that condition.

By my improved construction the tire is not only firmly attached to the center and lateral displacement in either direction prevented, but the tire is secured in such a way that it will remain on the center if broken while running, and the expense and labor of making the wheel are materially reduced.

I claiml. The herein-described car-wheel, consisting of a metallic wheel-body provided with outwardly-Haring bevels on its outer edge, one on each side, and a continuous rolled tire, provided with two fianges on the inside, said tire being contracted by hydraulic pressure to fit said body, and the flanges lon the inner part of the tire being bent inwardly to engage with the bevels on the wheel-body, whereby the amount of pressure exerted upon the tire for contracting it upon the periphery and sides of the wheel-body may be regulated with exactness, substantially as described.

2. The herein-described car-wheel, consisting of a wheel-body, turned true on its outer edge and provided with outwardly-Haring bevels on said edge, one on each side, and a continuous rolled tire, provided with a flange on its outer edge and with two flanges on its inner edge, the outer of these flanges being thicker und longer than the inner one, said und sides of the wheel-body may be regulated tire being' contracted by hydraulic pressure with exuetness, substantially as described. so as to llt; said body and Ialle l'lzmges on the inner edge of said tire being'bent inwardly 5 to engage lalle bevels on the Wheel-body, fituessesz JONATHAN ll. \VES'l`.
